Low-Carbon, Bio-Based Sustainable Aviation Fuel

To reduce the environmental impact of aviation, biofuel for jets is a key aspect for the future, because it offers an immediate impact on the carbon footprint.

Our renewable low-carbon jet fuels can be used in today’s aircraft. Our Alcohol-to-Jet Synthetic Paraffinic Kerosene (ATJ-SPK) is Sustainable Aviation Fuel (SAF) that is one of the few non-fossil-based alternative jet fuels available for commercial use.

Since it is ready to replace petroleum-based jet fuel, it meets or exceeds the standards in ASTM D1655/7566 specification, which specifies blending up to 50 percent (though we’ve flown test aircraft on 100-percent SAF).

  • For flash point, the standard stipulates a 38 degrees C minimum, and ATJ is well within acceptable range at 45 to 50 degrees C.
  • Both also pass the standard for thermal oxidation stability.
  • For freezing point, the standard requires -40 degrees C maximum for Jet A and -47 degrees C for Jet A-1, and Jet A-1 complies with -50 degrees C, while ATJ is -78 degrees C.
  • The energy density standard is 42.8 MJ/kg minimum, and Jet A-1 complies with 42.9 MJ/kg, while ATJ has 44.0 MJ/kg.
  • The total sulfur content standard is 0.3 percent max, while Jet A-1 comes in at 0.05 percent and ATJ rates at less than 0.00 percent.

Sustainable Aviation Fuel Opportunities

In the video below, we show how airlines can benefit from sustainable aviation fuel in the near-term, and achieve their goals to reduce carbon emissions.

This means airlines, air freight haulers, and private aviation will be able to lower the carbon footprint of their equipment immediately as SAF is produced and distributed, without waiting for new aviation technology to be developed, accepted, and commercialized. And it can work with the current petro-based fuel delivery systems.
